Not this 1.4, well not without lots of mods, the eaisiest way to go for modding the 25/zr engine is to get the 1.8l vvc engine, it uses the standard 1.8 block but with a vvc head, the vvc head uses much bigger valves and cams to compensate, then there are lots of companys that provide performance cams for the vvc and forged pistons for the block ect, mods seem to start more commonly for these engines at 1.6 although the 1.4 zr engine (the engine in the pic) is a slightly uprated version of the 1.4 25 engine. Back to the vvc engine, people usually add a small turbo like a T2 but you can go bigger if you have the money, they also use this engine very commonly in the caterham 7 but they don't put a turbo on because theres not really enough room under the hood.
Iv just discovered the weight of the car. The 3 door weighs 1020kg and the 5 door weighs 1040kg, mines the 5 door but iv still got a pretty light car i think.
EDIT: Heres some candy....
